[PATCH] Leak in vesafb

[Felipe W Damasio]

	Hi Andrew,

	Patch against 2.6.0-test6.

	Releases a previous request'ed_mem_region. Found by smatch.

	Since it didn't checked the return value of request_region, I'm not 
sure we should free it here...since (as it says on the driver), 
"vgacon probably has this region already".

	Andrew, I'd appreciate you could review this..

	Thanks.

Felipe
